A new design of a microstrip rectenna at 5.8 GHz for wireless power transmission applications

Abstract

<span>Due to the ever-increasing power demand, the need of electricity and eco-friendly power in every nook and corner of the world, many reaserch topics have been devoted to deal with this problematic. This paper is taking part of the proposed solutions with the presentation of a novel 5.8 GHz rectenna system for wireless power transmission applications. In one hand, a miniaturized 5.8 GHz circular polarized patch antenna has been designed and simulated by using the Advanced Design System (ADS). In the other hand, a rectifier structure has been investigated and optimized by the use of the Harmonic Balance method available in ADS. The circuit is based on 5 HSMS2820 Schottky diodes implemented in a voltage multiplier topology and a load resistance of 1 KOhm. Both of the structures have been validated by simulation and experimental results and good agreement has been concluded.</span>

Improved design and performance of the global rectenna system for wireless power transmission applications around 2.45 GHz

“…In the literature, the existing works focus on the study of microstrip patch antenna (MPA) without considering the rectification circuit [1], [8]. These works are used to increase the performance of the microstrip receiving antenna in terms of gain, directivity, bandwidth, overall size, and adaptation to the port by choosing the shape of the patch [1], [9], the operating frequency (such as 2.45 GHz [1] and 5.8 GHz [10]), the characteristics of the substrate, and the type of polarization (such as linear polarization [11], circular polarization [12], [13]). Other works focus on studying the rectifying circuit without considering the antenna [14].…”

A new structure of a wide band bridge power limiter

“…However, it is possible to generate the necessary DC biasing current by choosing Zero-Bias diodes [21,22] and using a detector diode as shown in Figure 2. The detector diode will transform a part of incident signal to DC current as used in rectenna systems [23,24]. On the other hand, the return DC current is ensured by an RF Choke or by the limiter diode itself.…”

A rectangular CSRR based microstrip UHF reader patch antenna for RFID applications

“…The metamaterial CSRR antennas is one among the growing research topic in the field of compatible antennas. These techniques has various advantages because of their improved performance in terms of the band of operation [11][12][13][14][15].…”
